Voltage conversion on Accuphase DP900-DC901

Thanks, but I knew that each accuphase device allows to be connected to 100v, 110v and 230v just setting the power transformer; so I would choose this way to eliminate a further trasformer.

In the meantime, I found an interesting 3d here on audiogon about the conversion of an accuphase amplifier, but inside there is also a reference about the combo I asked. As I expected, it seems that is possible to convert the devices, even if, unfortunately, I can't open the photos attached, I think because they are too old...

I would just buy plain 220 to 100V transformer. Devices are not power amps where current limit may be an issue. Just make sure transformer is rated at least 2x times rated power consumption. Make sure it is just a transformer and not some sort of a switching power supply or inverter. I.e. no electronics, just big transformer.
